An aluminum cap which serves as a cover to a glass pyrex jar is tightly attached to the glass; To open the jar, it was exposed to a hot water bath and the temperature was noted at 70 Celsius. The inside diameter of the cap is 6.0 cm at 30 Celsius. Find the difference in radius (cm) that will result from this method The constants needed for the problems are tabulated below. Metal alloy Substance B calorimeter Substance A ice Specific heat ( J/g C) 2.00 3.00 0.900 2.50 2.10 Heat of fusion of water = 333kJ/kg Specific heat water= 4.186 J/g C Heat of vaporization of oxygen= 213 kJ/kg Heat of vaporization water 2260 kJ/kg
